看到网站上计算最佳指数因子（OIF）的程序只考虑了原始波段的20种组合，我的这个可以任意多个波段，并且自动排序-See calculates the optimum index factor (OIF) on the website is only considered 20 possible combinations of the original band, this can be any number of my band, an

波段组合OIF指数计算，求一幅数字图像的熵值(Band combination OIF index calculation, seeking a digital image entropy)

计算遥感数据3个波段组合的OIF指数，给出OIF最高的10种组合(The OIF index of three bands combination of remote sensing data is calculated, and the top 10 combinations of OIF are given.)

1.计算高光谱各个波段的OIF指数 2.根据OIF指数确定高光谱数据的最佳3个波段组合(Calculating the OIF index of hyperspectral bands Determine the best combination of three bands of hyperspectral data according to OIF index)
